Yes it's a well specc'd car in good condition, and certainly at the top end of the market. The only point of contention would be where the top end is priced.
Tec II kit is a great value adder, although it does look a bit odd with a "standard" spoiler on the boot and not the Tech II wing, or even a Tech I. The after market wheels do look great, but are possibly not everyone's cup of tea.
Factory premiumn sounds (fader and door tweeters) plus the OBC are also good features and worth a higher asking price.
Hard tops were mega-expensive when new, circa GBP 3k IIRC. I sold mine in the UK as I never used the car in winter so had no use for it (it was practically brand new) for nearly two grand (pounds). Most E30 Cabs are now sunny summer day drivers only so the demand for hard tops is practically nil, can pick them up for a couple of hundy now.
As for the wind deflector - there is a reason why you don't see many of them around!
Biggest detractors from the vehicle would be 1) it's an auto which in an E30 is not a good box, even with the selector switch thingy which this has 2) the interior colour - yes it's leather and in great nick, but beige is not a great look for most people look for an E30 'vert these days.
If you are in no rush to sell then that is great, the right buyer will come along eventually.
